Description

  The present invention can stably store a bundle of paper towels or the like in which a plurality of unit papers are stacked, and can take out approximately one sheet at a time even when the unit paper bundle becomes a few remaining sheets. About.

  Conventionally, when a unit paper (a piece of paper that can be taken out at once: a paper towel, etc.) is stacked and stored in a container body, the unit paper is taken out one by one from a unit paper outlet formed at the bottom of the storage part. At the same time, a paper towel cabinet with the structure that the next unit paper is pushed out to the unit paper outlet is used for toilets on each floor in large buildings such as hospitals, convenience stores, nursing homes, health facilities for the elderly, department stores, hotels, restaurants, etc. It is installed as a sanitary instrument.

  In such a paper towel cabinet, when the stack of unit paper stacks is less than ten or less, if you try to pull out the paper towel, all of the remaining one will pop out at once, causing inconveniences that are wasted frequently. It was. In other words, when a large number of paper towels are stacked and stored in the cabinet, the total weight of the paper towel will be applied to the lower paper towel, and the weight will be dragged excessively when taking out one paper towel at a time. Can be taken out accurately one by one.

However, since the amount of paper towels became a small amount, such as a dozen or so, the weight of the conventional type of cabinet paper towels became extremely light, almost no pressure from above was applied to each paper towel, When the paper towel is taken out from the cabinet, the second-order paper towel is dragged excessively from the cabinet, and the inconvenience that the second-order paper towel or all the paper towels pop out frequently occurs. This is a problem as a waste of paper towels and a waste of resources.

  In order to solve the above-described problem, there is one in which guide ribs are provided along the vertical direction in the cabinet as in Patent Document 1. The rib is a tapered member that gradually protrudes into the cabinet as it goes downward. However, even if such a solution is taken, if the remaining number is 10 or less, it may be difficult to take out one sheet at a time. Therefore, the problem (technical problem or purpose) to be solved by the present invention is that it is stable to take out one sheet at a time even if the unit sheet bundle is a few remaining sheets (for example, ten or more sheets). It is to realize what can be done.

  Therefore, as a result of intensive researches to solve the above problems, the inventor has found that the invention of claim 1 is stored as a multi-layer stack of unit papers, and the unit papers are continuously conveyed one by one from the multi-layer bundle.

According to a third aspect of the present invention, in the paper towel cabinet according to the first or second aspect, the upper end position of the upper bulge of the width side support piece is located above the position of the locking surface of the front and rear side support piece. As a result, the above problems were solved.

  The invention according to claim 4 is the paper towel according to any one of claims 1, 2, or 3, wherein the lower bulge is formed to have a larger bulge amount from the wall surface than the upper bulge. By using a cabinet, the above problems were solved. The invention of claim 5 is a paper towel cabinet according to any one of claims 1, 2, 3 or 4, wherein the lower protruding slope is formed as a gentler slope than the upper protruding slope. The above problem has been solved. The paper towel according to claim 6, wherein the inner side cross-sectional shape perpendicular to the width direction of the lower portion of the main body is formed in an arc shape in the description of any one of claims 1, 2, 3, 4 or 5. By using a cabinet, the above problems were solved.

  The invention according to claim 7 is the invention described in any one of claims 1, 2, 3, 4, 5 or 6, wherein the width side support piece is integrally formed with a bottom guide plate from the lower end of the lower bulge. The width side support piece pieces are formed such that the edges of the bottom guide plates face each other at a predetermined interval, and the width side support piece pieces are arranged on the front inner wall surface and the rear side of the lower part of the main body. By being mounted on the inner wall surface through fixing means, both the bottom guide plates are installed on the bottom surface, and the paper towel cabinet in which the gap between both edges is located on the extraction opening, Solved the above problem.

  According to an eighth aspect of the present invention, in the seventh aspect of the present invention, the fixing means includes a locking portion formed on a reinforcing rib formed on an upper end of the width-side support piece of the width-side support piece piece and a lower surface side of the bottom portion guide plate. And the said subject was solved by making it the paper towel cabinet by which the to-be-latched part which the said latching part latches was formed in the front side inner wall surface of the said main body lower part, the rear side inner wall surface, and the bottom face.

  The invention of claim 9 is the fitting according to any one of claims 1, 2, 3, 4, 5, 6 or 7, wherein a fitting portion is formed on the back side of the front and rear side support pieces. A fitting piece having a fitting projection and an end plate to be fitted and connected to the portion is provided, and the fitting piece is inserted only into the fitting projection from the outside of the lower part of the body on the inner wall surfaces of both sides of the lower part of the body. A paper towel in which a possible connection through-hole is formed, a fitting protrusion of the mounting piece is inserted into the connection through-hole, and the back side of the front and rear side support pieces is fitted and fixed to the mounting piece By using a cabinet, the above problems were solved.

  According to the first aspect of the present invention, in the storage body, a zigzag shape or a sawtooth is formed on the inner wall surface of the lower part of the main body by the upper projecting slope, the lower projecting slope, and the locking surface located between the upper projecting slope and the lower projecting slope By having front and rear side support pieces formed in a shape, and having a wide side support piece consisting of an upper bulge and a lower bulge that are vertically adjacent to the front inner wall surface and the rear inner wall surface, When the remaining amount of paper towels (unit paper) is very small, it prevents the remaining unit papers from being dragged out when one unit paper is taken out. It can be taken out.

  The above effect will be described in detail. When the remaining amount of unit papers constituting the multi-layer bundle becomes a small number (less than ten sheets, particularly less than ten sheets), the unit paper is supported by both front and rear side support pieces and both width side support pieces. The periphery of the paper can be fixed with an appropriate force. That is, in the front and rear side support pieces, the upper projecting slope, the locking surface, and the lower projecting slope are formed in a sawtooth shape or a zigzag shape, and the width side support piece is composed of an upper bulge and a lower bulge. It has been done.

  With such front and rear side support pieces and width side support pieces, the lowermost unit sheet of the stack of stacks is suppressed by the locking surface of the front and rear side support pieces, and the lower side bulge of the wide side support pieces Supported by the article. As a result, when taking out the lowermost unit paper from the take-out opening of the cabinet, a large bend operation is generated on the entire multi-layer bundle together with the unit paper, and the situation where the alignment state of the multi-layer bundle is disturbed, When the lowermost unit sheet is taken out, it is possible to prevent the next unit sheet or all remaining unit sheets from being dragged out.

  As a result, the remaining number of unit papers in the multi-layer bundle becomes small, and even when all the unit papers are taken out once and it is easy to be pulled out from the cabinet at a time, the unit papers are accurate one by one until the end. And it can take out reliably and can eliminate uselessness. In addition, the front and rear side support pieces and the width side support pieces are extremely simple in shape and configuration, and can be easily attached to the lower portion of the main body. This can also be installed in a conventional type cabinet.

  In the invention of claim 2, since the cross-sectional shape of each of the upper bulging strip and the lower bulging strip of the width side support piece is a semicircular shape, it supports the lower layer portion of the multi-layer bundle of the width side support piece paper towel. In addition, the paper towel that is pulled out can smoothly move the support of the next paper towel from the upper bulging strip to the lower bulging strip, so that the paper towel can be pulled out stably.

  In the invention of claim 3, since the upper end position of the upper bulging strip of the width side support piece is configured to be located above the position of the locking surface of the front and rear side support pieces, the lowermost paper towel is Four sides are supported in a constant state by the width side support pieces on both sides in the front-rear direction and the locking surfaces of the front and rear side support pieces on both sides in the width direction. It is possible to carry out until only one sheet is pulled out from the bundle of paper towels with the remaining few.

  In the invention of claim 4, the lower bulging strip is formed so that the amount of bulging from the wall surface is larger than that of the upper bulging strip. Since the bulge is smoothly guided from the bulge to the lower bulge, and the lower bulge has a large bulge, it serves as a stopper for the lowermost paper towel. When taking out, it can be taken out easily and wasteful paper discharge can be prevented.

  In the invention of claim 5, since the lower projecting slope is formed as a gentler slope than the upper projecting slope, the movement from the upper projecting slope to the lower projecting slope is performed smoothly, and from the lower projecting slope, Along with the lower bulge of the width side support piece, a force that slightly resists the downward movement of the lowermost paper towel is generated, thereby preventing wasteful paper discharge. In the invention of claim 6, the inner side cross-sectional shape orthogonal to the width direction of the lower part of the main body is formed in an arc shape, so that the movement of the unit paper is smooth even when contacting the bottom surface in the paper towel take-out operation, A good take-out operation can be achieved.

  In the invention of claim 7, the width side support piece comprising a width side support piece and a bottom guide plate integrally formed from the lower end of the lower bulging strip of the width side support piece 3, which is a separate material from the lower part of the main body. Each of the two bottom side guide pieces on the front inner wall surface and the rear inner wall surface of the lower part of the main body. It is configured to be mounted via a fixing means. Thereby, the width side support piece can be easily and quickly assembled to the lower part of the main body. In addition, the bottom guide plate has a cross section perpendicular to the longitudinal direction and has a circular arc shape that protrudes downward, so that the bottom of the main body has a substantially flat left and right side in the front-rear direction. A symmetrical arc-shaped bottom surface can be formed.

  According to an eighth aspect of the present invention, the fixing means includes an engaging portion formed on a reinforcing rib formed on an upper end of the width side supporting piece of the width side supporting piece piece material and a lower surface side of the bottom portion guide plate, and the main body. The lower front inner wall surface, the rear inner wall surface, and the bottom surface are formed with a locked portion to be locked by the locking portion, so that the locking portion of the wide side support piece piece material can be By locking to the to-be-latched portion, the wide side support piece material can be easily attached to the lower part of the main body without using a fixing tool such as a screw or an adhesive.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The paper towel stored in the paper towel cabinet in the present invention includes various sanitary papers, kitchen papers, and the like in addition to the commonly used paper towels. The paper towel and the other paper described above are hereinafter referred to as unit paper c. A plurality of unit sheets c, c,. The paper towel cabinet of the present invention is mainly composed of a storage body 1 for storing a multi-layer bundle C and a lid body 4 that covers the storage space for the multi-layer bundle C of the storage body 1 so as to be freely opened and closed.

  The storage body 1 includes a main body lower portion 11 and a main body upper portion 12 (see FIGS. 1A and 1B). The main body upper part 12 has a storage space for storing the multi-layer bundle C (see FIGS. 1A and 1B). Further, the lid body 4 is mounted on the storage body 1 through the pivoting portion 5 so as to be openable and closable with respect to the front side of the storage body 1 (see FIGS. 1A and 1B). ]. The cover body 4 is formed on the front side from a cover portion front surface 41 and cover side portions 42 and 42, and the cover portion front surface 41 covers the front side of the storage body 1 when the cover body 4 is closed with respect to the storage body 1. And both the said covering side parts 42 and 42 coat | cover both the width direction both sides of the storage body 1 (refer FIG. 1 (B)).

  When the lid 4 is opened from the storage body 1, the front side of the storage body 1 is substantially fully open, and a multilayer stack C of a plurality of unit papers c, c,. It can be done. In addition, although not particularly illustrated, a lock portion or the like for maintaining the covering (closing) state of the lid body 4 with respect to the housing body 1 by fitting between the housing body 1 and the lid body 4. Is provided.

  The main body lower portion 11 is a portion that occupies the lower side of the storage body 1 and is formed in a substantially rectangular tray shape. The main body lower portion 11 includes a bottom surface 11a, side inner wall surfaces 11b and 11b on both sides in the width direction, a front inner wall surface 11c on the front side in the front-rear direction, and a rear inner wall surface 11d on the rear side in the front-rear direction. Here, the width direction of the storage body 1 including the main body lower portion 11 indicates the lateral direction when the storage body 1 is viewed from the front, and is the left-right direction in FIG. It shows the depth when viewed from the front of the body 1, and is in the left-right direction in FIG. The width direction and the front-rear direction described above are also indicated by arrows in the other drawings.

  The bottom surface 11a of the main body lower part 11 has a cross-sectional shape orthogonal to the width direction formed in an arc shape (semicircular shape). An extraction opening 11e is formed in a long hole shape at the lowest position of the bottom surface 11a and along the width direction [FIGS. 1 (A) to (B), FIGS. 2 (A), (C), (D )reference〕. Further, on the outer side of the bottom surface 11a, main guide plates 11f and 11f are formed in a substantially hanging shape in the vicinity of both end edges in the front-rear direction of the extraction opening 11e and at the intermediate position in the width direction. Sub-guide plates 11g and 11g are formed in a substantially hanging shape on both ends (see FIGS. 1A to 1C, 2A, 2B, 3A, etc.).

  The main guide plates 11f and 11f and the sub guide plates 11g and 11g are formed so as to face each other substantially in parallel at the front and rear end edges of the extraction opening 11e. A gap is formed between the main guide plate 11f located in the middle along the width direction of the extraction opening 11e and the sub-guide plates 11g, 11g located on both sides in the width direction. Has been. The voids are referred to as extraction void portions 11h and 11h [see FIG. 1 (A), FIG. 2 (A), FIG. 3 (A), etc.].

  The width direction dimension of the extraction opening 11e is slightly larger than the width direction dimension of the unit paper c of the multi-layer bundle C housed in the storage body 1. Then, when one unit paper c is taken out, a part of the unit paper c protrudes so that the next unit paper c can be picked from the extraction opening 11e by being dragged by the drawn unit paper c. It is configured. A part of the unit paper c protruding from the extraction opening 11e is exposed to the extraction gaps 11h and 11h, and the user takes out the protruding part of the unit paper c from the extraction gaps 11h and 11h. Is.

  Further, there is an embodiment in which the main guide plates 11f and 11f, the sub guide plates 11g and 11g, and the extraction gaps 11h and 11h are not formed around the take-out opening 11e of the main body lower portion 11 in the storage body 1 ( (See FIG. 7). In this embodiment, the unit sheet c can be taken out from any position of the take-out opening 11e.

  The multi-layer bundle C is laminated while the unit papers c, c are engaged with each other so that each of the multiple unit papers c, c,... Is. That is, a structure in which each folded piece of the other two unit papers c folded in two is inserted on the opening side of one unit paper c folded in two is stacked in layers in the vertical direction. A bundle C is constructed. The multi-layer bundle C is a conventional product, and is often used for a paper towel dispenser according to the prior art.

  Front and rear side support pieces 2 and 2 are mounted on both side inner wall surfaces 11b and 11b in the width direction of the main body lower part 11 [FIGS. 1 (A) to (C), FIG. 2 (A), (C), ( See E)]. Further, width side support pieces 3 and 3 are mounted on the front inner wall surface 11c and the rear inner wall surface 11d of the lower body 11, respectively (FIGS. 1A to 1C, 2A and 2C). ), See (E)]. The front and rear side support pieces 2 and 2 serve to support the front and rear sides of the multilayer bundle C accommodated in the lower part 11 of the main body, and the width side support pieces 3 and 3 serve to support the width side of the multilayer stack C.

  Here, in the multi-layer bundle C, the unit paper c constituting the multi-layer bundle C is folded in half as described above, and the shape viewed from the plane in this state is a rectangle. The front and rear sides are short sides and are sides along the front and rear direction. The width side is a long side and is a side along the width direction (see FIGS. 2E and 13). When the unit paper c is stored in the storage body 1, the width of the unit paper c is aligned in the width direction at the lower body 11 of the storage body 1, and the front and back sides of the unit paper c are aligned in the front-rear direction. (See FIG. 9). The width side of the unit paper c is supported by the width side support piece 3 of the lower body 11, and the front and back sides of the unit paper c are supported by the front and rear side support pieces 2 of the lower body 11.

  The front and rear side support piece 2 is a member having an upper protruding slope 21, a locking surface 22, and a lower protruding slope 23. The front and rear side support pieces 2 are formed as separate members from the main body lower portion 11 and are paired together. The front and rear side support pieces 2 are fixed to the inner side wall surfaces 11b and 11b of the main body lower portion 11 with fixing tools such as screws and interposition members. It is what is done. In the front and rear side support piece 2, an upper projecting slope 21 and a lower projecting slope 23 are adjacent in the vertical direction, and a locking surface 22 is located between the upper projecting slope 21 and the lower projecting slope 23. .

  The upper protruding slope 21, the locking surface 22, and the lower protruding slope 23 are formed in a zigzag shape or a sawtooth shape. Specifically, the upper protruding slope 21 is a downward slope, and the locking surface 22 is formed so as to be once recessed from the lower end of the upper protruding slope 21. The locking surface 22 is a substantially horizontal surface formed facing downward.

  A lower projecting slope 23 is formed from the locking surface 22. The lower protruding slope 23 is a downhill inclined surface like the upper protruding slope 21. The upper projecting slope 21 and the lower projecting slope 23 are both formed in a substantially right triangle shape (or a human nose shape), and each of the slopes has an acute angle close to a right angle. It is formed as a gentler slope than the protruding slope 21.

  That is, if the angle of the upper protruding slope 21 with respect to the horizontal line Lh is θa and the angle of the lower protruding slope 23 is θb, then θa> θb (see FIG. 2B). The front and rear side support pieces 2 have a rectangular shape on the side surface, that is, the side that supports the multilayer bundle C. Furthermore, it is preferable that the corner | angular part of the lower end of the downward protrusion slope 23 is formed so that it may become circular arc shape (R). Thereby, the unit sheets c, c,... Can be smoothly taken out.

  The two front and rear side support pieces 2 and 2 are attached to both side inner wall surfaces 11 b and 11 b of the main body lower portion 11 so that the upper protruding inclined surfaces 21 and the lower protruding inclined surfaces 23 face each other. The respective positions in the front-rear direction and the mounting height with respect to the inner wall surfaces 11b, 11b of both the front and rear side support pieces 2, 2 are set to be the same position. The front-rear dimension of the front and rear side support pieces 2 is extremely small with respect to the front-rear dimension of the side inner wall surface 11b. Specifically, it may be about 10 mm to 30 mm, but is not particularly limited to the size range. It may be set as appropriate according to use conditions or paper quality.

  Further, the front and rear side support pieces 2 have a side surface in which the upper protruding slope 21 is formed in a rectangular shape and the lower protruding slope 23 is formed in a trapezoidal shape (see FIG. 6B). In the case where the lower projecting slope 23 has a trapezoidal shape, a substantially trapezoidal shape is also included [see FIG. 6C]. Some of the front and rear side support pieces 2 are formed in a trapezoidal shape from the upper projecting slope 21 to the lower projecting slope 23 (see FIG. 6D).

  Usually, most of the unit sheets c, c,... Of the multi-layer bundle C are supported on both front and rear sides by upper projecting slopes 21 and 21 of both front and rear side support pieces 2 and 2. And several sheets (specifically, about 10 sheets or less) of unit sheets c, c,... In the lower layer of the multi-layer bundle C are supported by the lower projecting slopes 23, 23 beyond both the locking surfaces 22, 22. The As described above, since the lower protruding slope 23 is formed with a gentler slope than the upper protruding slope 21, the resistance when the unit paper c moves downward when the unit paper c is pulled out of the cabinet from the extraction opening 11e. Is configured to be large. Further, the upper projecting slope 21 is steeper than the lower projecting slope 23, and the multilayer stack C supported by the upper projecting slopes 21 and 21 is stacked with the unit paper c on the lower layer side being pulled out. Although C descends, it is configured to be able to descend smoothly at that time.

  The width side support piece 3 is formed by an upper bulging strip 31 and a lower bulging strip 32 being adjacent to each other in the vertical direction [FIGS. 1 (A) to (C), FIG. 2 (A), ( See C) and (D)]. The upper bulging strip 31 and the lower bulging strip 32 are each formed in an axial shape. The axial directions of the upper bulging strip 31 and the lower bulging strip 32 are fixed to the front inner wall surface 11 c and the rear inner wall surface 11 d along the width direction of the main body lower portion 11. The upper bulging strip 31 and the lower bulging strip 32 are not separated, but are formed integrally (see FIG. 2D).

Further, the locked portion is only the lower locked portion 14 formed on the bottom surface 11a from the rear inner wall surface 11d side (see FIG. 10B).

  A locking protrusion 36 a is formed at the lower end of the lower locking portion 36. The locking protrusion 36a is formed along the lower end and the longitudinal direction of the lower locking portion 36, and is formed to bulge in the horizontal direction (see FIG. 8C). The lower locking portion 36 is inserted into the lower locked portion 14 formed on the bottom surface 11a near the rear inner wall surface 11d, and the locking protrusion 36a extends from the lower locked portion 14 to the lower portion 11 of the main body. It protrudes to the outside, and the locking protrusion 36a is locked to the lower locked portion 14 to fix the width side support piece piece A to the lower part 11 of the main body (see FIGS. 8 and 10B).

  In the width direction (longitudinal direction), the width-side support piece material A has a length dimension different from that attached to the front inner wall surface 11c side and that attached to the rear inner wall surface 11d. The width-side support piece piece material A attached to the inner wall surface 11c is formed shorter than the width-side support piece material A attached to the rear inner wall surface 11d.

  Specifically, the width-side support piece piece material A attached to the front inner wall surface 11c has a dimension approximately half or less in the longitudinal direction of the width-side support piece piece material A attached to the rear inner wall surface 11d. And the two width side support piece pieces A with which it mounts | wears with the front side inner wall surface 11c side are comprised, and it installs with a suitable space | interval in a longitudinal direction.

The picking opening 11m is an opening formed from an intermediate position in the longitudinal direction of the extraction opening 11e (the same direction as the width direction of the container 1) toward the front inner wall surface 11c. The picking opening 11 m is a part for picking out the unit paper c at the lowest position of the multi-layer bundle C stored in the storage body 1.

  In the second embodiment of the present invention, as other embodiment of the fixing means for the width side support piece piece material A and the main body lower part 11, although not particularly shown, the width side support piece piece material A has a locking portion. Without attaching the locked portion to the lower body portion 11, the wide side support piece piece material A is directly fixed to the main body lower portion 11 with a fixing tool such as a screw, or the wide side support piece piece material A and The lower body 11 may be attached with a double-sided adhesive tape. In the storage body 1 according to the embodiment of the present invention, the pivoting portion 5 in the opening / closing operation of the lid body 4 is provided at the position of the upper end and the front end of the storage body 1. That is, the lower end of the lid body 4 opens and closes according to the arc locus with the pivoting portion 5 as the center of rotation (see FIG. 8A).

  Next, in 3rd Embodiment of this invention, it is a structure regarding the adhering means of the front-and-back side support piece 2. FIG. The front and rear side support pieces 2 are substantially the same as the front and rear side support pieces 2 in the first embodiment, and have an upper projecting slope 21, a locking surface 22, and a lower projecting slope 23. And the fitting part 24 is formed in the back side of the front-and-back side support piece 2, and the attachment piece 6 fitted and connected to this fitting part 24 is comprised [FIG. 11 (A), (B). reference〕.

  The fitting portion 24 is formed with two fitting protrusion plates 24a and 24a at appropriate intervals in the vertical direction from the back side of the front and rear side support pieces 2 (see FIG. 11A). On both fitting protrusion plates 24a and 24a, fitting protrusions 24b and 24b in the form of vertical plates are formed toward the other side. A small protrusion 24b 'is formed at a longitudinal intermediate position between the fitting protrusions 24b and 24b. Further, the attachment piece 6 includes a fitted protrusion 61 and an end plate 62.

  The fitted protrusion 61 has a fitted groove 61 a formed along the circumferential direction of the fitted protrusion 61. Further, a small recess 61a 'is formed in the fitting groove 61a. The fitting protrusions 24b and 24b are inserted into the fitting groove 61a, the small protrusion 24b ′ is fitted into the small depression 61a ′, and the front and rear side support pieces 2 and the mounting piece 6 are joined together. 11 (D), (E)].

  Further, on both side inner wall surfaces 11b and 11b of the lower part 11 of the main body, connection through holes 11p and 11p are formed. The connecting through-hole 11p can be inserted only by the fitting protrusion 61 of the mounting piece 6, and the end plate 62 is in contact with the peripheral edge of the connecting through-hole 11p. That is, the end plate 62 serves as a stopper that restricts the insertion of the attachment piece 6 and serves as a cap of the connection through hole 11p (see FIG. 11D).

  And the fitting protrusion 61 of the said attachment piece 6 is inserted in the said connection through-hole 11p, and both the fitting parts 24 of the back side of the said front-and-back side support piece 2 are inward of the main body lower part 11. FIG. The fitting protrusions 24b and 24b formed on the fitting protrusion plates 24a and 24a are bitten so as to slide in the fitting groove 61a of the fitting protrusion 61 of the mounting piece 6 from the front-rear direction. . As a result, both the fitting protrusions 24b and 24b are inserted into the fitting groove 61a, the small protrusion 24b ′ is fitted into the small recess 61a ′, and the front and rear side support pieces 2 are attached to the inner wall surfaces 11b on both sides by the attachment pieces 6. , 11b (see FIG. 11D).

  FIG. 12 is a modification of the shape of the lower projecting slope 23 of the front and rear side support piece 2. 12 (A) and 12 (B), a spherical bulging portion 23a is formed on the lower projecting slope 23. FIG. The bulging portion 23a has a clear boundary with the inclined surface of the lower projecting slope 23. FIG. 12C shows a shape in which the boundary between the inclined surface of the lower projecting slope 23 and the bulging portion 23a changes gently.

  In the present invention, the unit sheets c can be taken out one by one from the lower opening side of the multi-layer bundle C stored in the storage body 1 through the extraction opening 11e of the lower body 11. When a large number of unit papers c, c,... Remain, the multi-layer bundle C is supported by the front and rear side support pieces 2, 2 and the wide side support pieces 3, 3, and the lower unit paper c, The weight of the multi-layer bundle C is applied to c,..., and the load due to the weight acts appropriately so that the unit papers c, c,. be able to.

  Next, the process of taking out the unit paper c when the remaining number of unit papers c, c,... Of the multi-layer bundle C has become small will be described mainly with reference to FIGS. Here, a small amount of unit papers c, c,... Is conventionally assumed to be 10 sheets or less, which is said to be most easily discharged in a bundle. Actually, the small number of sheets may exceed 10 sheets, or may be in the single digit range of 9 sheets or less. In the figure, the multilayer stack C is shown with the gap between the unit papers c and c larger than the actual size and expanded in the height direction. The process of taking out the lowermost unit paper c of the bundle C from the take-out opening 11e is made easier to understand.

  The multi-layer bundle C composed of a small amount of unit papers c, c,... Has a slight weight, and in the conventional one, no load is applied to the unit paper c to be taken out and the next unit paper c meshing with the unit paper c. It is equal to not taking. Therefore, it is dragged by the unit paper c to be taken out and drops to the next unit paper c from the take-out opening 11e. Further, in some cases, the next unit paper c further pulls out the next unit paper c, and as a result, a plurality of unit papers c, c,...

  FIG. 4 is a process chart for taking out the unit paper c from the multi-layer bundle C whose remaining number is small. In the present invention, the unit sheets c, c,... Of the multi-layer bundle C whose remaining number is small are unit widths along the width direction of the unit sheets c, c,. Supported by the pieces 3 and 3. Specifically, the lowermost unit paper c of the multi-layer bundle C is supported by the lower bulges 32, 32 of both width side support pieces 3, 3, and the unit paper c, which is above the lowermost unit paper c, c, ... are in a state of being supported by both upper bulging strips 31, 31 [see Fig. 3 (C), Fig. 4 (A), (C), (E)].

  The unit paper c in the lowermost layer is not supported by the upper bulging strips 31, 31 due to the weight of the unit paper c, c,... Above it, and the positions of the lower bulging strips 32, 32. And will be supported. Further, even if the number of unit papers c, c,... Above the lowermost unit paper c is about two or three, the lowermost unit paper c is thin and flexible. It will be supported by both lower bulges 32 and 32 as well.

  In the present invention, both front and rear sides of the unit paper c in the vicinity of the lowermost layer of the multi-layer bundle C whose remaining number is small are supported by both front and rear side support pieces 2 and 2. Specifically, the unit papers c, c,... In the vicinity of the lowermost layer of the multi-layer bundle C are bent downward at the front-rear side middle portion [see FIG. , 22 (see FIG. 3 and FIGS. 4B, 4D, and 4F), and receives a reaction force F from the gently inclined surfaces of the lower projecting slopes 23, 23, and is in a natural state. The stable storage state of the multi-layer bundle C (unit papers c, c,...) Is maintained.

  That is, the unit papers c, c,... Near the lowermost position of the multilayer stack C and the unit papers c, c,. Separately (see FIG. 3B), the unit papers c, c,... Near the lowermost layer are supported by the lower projecting slopes 23, 23, and the unit papers c, c,. It will be supported by the slopes 21 and 21 (refer to FIG. 3 (B), FIG. 4 (B), (D), (E)).

  When the lowermost unit paper c of the multi-layer bundle C is taken out from the take-out opening 11e, the unit paper c partially protruding from the take-out opening 11e by the main guide plates 11f and 11f and the sub guide plates 11g and 11g has a width of It is exposed to the extraction gaps 11h, 11h on both sides in the direction, and is taken out by pinching the exposed portion of the unit paper c with both hands. When the lowermost unit paper c is taken out in this way, the unit paper c is drawn out with good balance. In the multi-layer bundle C, the lowermost unit paper c and the upper unit papers c, c,... 22 makes a pseudo-separated state.

  Further, in the width direction of the multi-layer bundle C, the lowermost unit paper c is supported by the lower bulging strips 32, 32 of both width side support pieces 3, 3, and the unit paper above the lowermost unit paper c. c, c,... are supported by both upper bulging strips 31, 31. In the prior art, when the lowermost unit paper c of the multi-layer bundle C is taken out from the take-out opening 11e, the lowermost unit paper c operates so as to twist in the take-out process, and the bend operation extends over the entire multi-layer bundle C. Therefore, the orderly stacked state of the multi-layer bundle C is disturbed, and the storage state with respect to the storage body 1 becomes extremely unstable. As a result, the multi-layer bundle C is easily dropped off at a time.

  In such a situation, in the present invention, both locking surfaces 22 and 22 of both front and rear side support pieces 2 and 2 act so as to press down the lowermost unit paper c, and both width side support pieces. 3 and 3, the lowermost unit paper c is in a state in which both width sides bite into a hollow portion between the upper bulging strip 31 and the lower bulging strip 32 adjacent to each other in the vertical direction. Supported.

  Therefore, the bend operation in the take-out process of the lowermost unit paper c is minimized, and the storage state of the multi-layer bundle C in the storage body 1 can be stabilized to the end. Only the lowermost unit paper c of the bundle C is in a state where it is difficult to affect other unit papers c. Therefore, when the lowermost unit paper c of the multi-layer bundle C is to be taken out, the unit paper c is normally guided so that a part of the next unit paper c protrudes from the take-out opening 11e. Only the operation is performed, and the unit paper c can be taken out from the multi-layer bundle C one by one accurately and reliably (see FIGS. 4C and 4E).

  Further, when the lowermost unit paper c of the multi-layer bundle C is taken out from the extraction opening 11e, the next unit paper c is removed from the upper swells 31 and 31 of the both width side support pieces 3 and 3 from both lower swells. It can be easily moved to the position of the protrusions 32 and 32. In particular, in the embodiment in which the cross sections of the upper bulging ridge 31 and the lower bulging ridge 32 are formed in a semicircular shape, the unit paper c is almost without resistance from both the upper bulging ridges 31, 31, 32.

  Further, in both the front and rear side support pieces 2 and 2, the upper protruding slope 21 is steeply inclined and the lower protruding slope 23 is gently inclined, so that the unit paper c is protruded from both the upper protruding slopes 21 and 21. 23 and 23, and the unit paper c moved to the lower projecting slopes 23 and 23 has a larger resistance F from the inclined surface, and the unit paper c can be easily moved downward except in the take-out operation. It can be prevented from falling [see FIG. 3 (B), FIG. 4 (D), (E)].

  Further, in the main body lower portion 11 of the storage body 1, the position of the extraction gap portion 11 h existing between the main guide plate 11 f and the sub guide plate 11 g is set at one end side in the width direction of the main body lower portion 11. [See FIG. 1 (A), FIG. 2 (A)]. Therefore, when taking out the lowermost unit paper c from the take-out opening 11e, a part of the unit paper c exposed in the take-out gaps 11h and 11h provided at both sides in the width direction of the take-out opening 11e If it is picked up and taken out only from either one of the extraction gaps 11h, the lowermost unit paper c is easily taken out in an inclined state [the display portion of the unit paper c by a two-dot chain line in FIG. reference〕.

  Therefore, a moment M to rotate is applied to the lowermost unit paper c (see FIG. 3A), and the opposite side of the unit paper c jumps upward with respect to the side holding the unit paper c. And the orderly stacking state of the multi-layer bundle C is disturbed, so that when the lowermost unit paper c is taken out, it is dragged to the next unit paper c or all the remaining unit papers c, c,. There is a risk of being.

  Even when the lowermost unit paper c is rotated by this moment M, the reaction force F is generated on both the locking surfaces 22 and 22 of the front and rear side support pieces 2 and 2 as described above, and the lowermost unit paper c. The sheet c is suppressed (see FIGS. 3A and 3B), and the rotation operation at the time of taking out due to the inclined state of the unit sheet c is prevented, so that the unit sheet c can be taken out stably. Similarly, both width sides of the lowermost unit paper c are substantially locked in a recess between the upper bulging strip 31 and the lower bulging strip 32 adjacent to the upper and lower sides of the both width side supporting pieces 3 and 3. Thus, the rotation operation of the unit paper c in the front-rear direction can also be prevented (see FIG. 3C).

  Next, FIG. 5 shows the process of taking out the unit paper c when the remaining number of unit papers c, c,... Of the multi-layer bundle C is further reduced. Is the case. In the multi-layer bundle C, the lowermost unit paper c is supported in the width direction by the lower bulging strips 32, 32 of both width side support pieces 3, 3, and the unit paper c, upper than the lowermost unit paper c, c,... are supported by both upper bulging strips 31, 31. In addition, a small number of unit papers c, c,... Are bent downward substantially so that the entire multilayer stack C is locked by the locking surfaces 22, 22, and the lower projecting slopes 23, 23. Reaction force F from the gently inclined surface (see the arrow by the dotted line in FIG. 5B) is generated, and in a natural state, the unit sheets c, c,... Are maintained in a stable state [FIG. (See (A), (B)).

  When the lowermost unit paper c is operated so as to be twisted in the take-out process, the entire multi-layer bundle C is twisted, and the unity sheets c, c,... Although the storage state inside the body 1 is likely to be unstable, as described above, the entire multi-layer bundle C presses the multi-layer bundle C downward by the two locking surfaces 22 and 22 and the width side support pieces 3 and 3. , While supporting the unit papers c, c,... So as to be hooked between the upper bulging strip 31 and the lower bulging strip 32 (see FIGS. 5A, 5C, 5E). The lower bulging ridge 32 protruding into the inside of the lower portion 11 of the main body 11 receives the unit papers c, c,... And acts so that a plurality of unit papers c, c,.

  As a result, even when the remaining unit papers c, c,... Of the multi-layer bundle C are about two or three sheets, the bending operation in the take-out process of the lowermost unit paper c is minimized, and the unit papers c, c,. .. are not easily disturbed, the storage state of the multilayer bundle C in the storage body 1 is stabilized, and the unit sheets c can be reliably taken out one by one until the end [FIG. ) To (F)].
